| 04/25/22 00:07:44 | Possibly detected | 42.2920 | -70.3177 | There are classified and unclassified singlets throughout the period but it’s difficult to distinguish them
from HW downsweeps. There are two possible doublets in P2 and near the end of P3, but they both have
fairly short downsweeps and could also be HW. |
| 04/25/22 05:07:44 | Possibly detected | 42.2914 | -70.3767 | Classified (P13 and 16) and unclassified singlets throughout the period with no obvious signs of HW song. |
| 04/25/22 07:07:44 | Possibly detected | 42.2908 | -70.4052 | There are a couple of longer downsweeps in P10 that could be SW but I’m not convinced that they aren’t
possibly part of the patterned HW downsweeps. |
| 04/25/22 12:07:44 | Possibly detected | 42.3014 | -70.4598 | One possible unclassified doublet in P8 that is isolated from the HW song. |
| 04/25/22 18:07:44 | Possibly detected | 42.3252 | -70.5027 | One unclassified doublet in P13. The downsweeps are shorter like the HW doublets but there aren’t any
others in a pattern. |
| 04/25/22 19:07:44 | Possibly detected | 42.3302 | -70.5003 | One unclassified doublet in P16 but it could also be HW, there are a couple of random moans in P14 and
16. |
| 04/25/22 19:22:44 | Possibly detected | 42.3315 | -70.4997 | One classified doublet in P2 but the downsweeps are shorter and steeper like HW doublets. There’s no
sign of patterned calling here though. |
| 04/25/22 20:22:44 | Possibly detected | 42.3320 | -70.5014 | This is a decent example of when there are downsweep doublets incorporated into the HW song. There’s
a classified single downsweep in P3 but it’s extremely faint and could still be HW. There’s also a loud
doublet in P4 (the one connected to the long yellow artifact) that looks like it’s overlapping with a HW
doublet, but it’s still difficult to isolate it as a SW doublet. |
| 04/25/22 21:07:44 | Detected | 42.3343 | -70.4996 | Classified triplet(?) in P1-2 that’s overlapping with a short HW downsweep, and a classified doublet in P2-
3. Other possible singlets throughout the period but it’s difficult to distinguish between SW and HW. |
| 04/25/22 22:07:44 | Possibly detected | 42.3372 | -70.4971 | Classified singlet in P6 and probable unclassified SW doublet in P5. |
